Stay Informed about H1N1 Flu

Each week CDC analyzes information about influenza disease activity in the United States and publishes findings of key flu indicators in a report called FluView.

This algorithm is designed to assist physicians and those under their supervision in identifying indicators of and responses to symptoms of flu-like illness (i.e., fever with cough or sore throat). (NOTE: this guidance is not intended for use by the general public and is not a substitute for sound clinical judgment.)
